Abstract: Shift register is a common device for generating signals and sequences. Usually register is the combination of flipflops.The shift register is of two types which are: linear and nonlinear. Various sequences including pseudorandom codes are generated by linear and nonlinear feedback shift registers, respectively. Linear feedback shift register (LFSR) is composed of dynamic or static master-slave flip-flop. Its characteristics are usually characterized by a characteristic polynomial. The twoinput XOR gate is used to calculate the characteristic polynomial of the maximum or near maximum length of the feedback function without rectifying the register.
